A young woman and a girl standing beside a bathing machine at the seaside in about 1900. Bathing machines were designed to protect the modesty of bathers. Pulled to the edge of the sea by horses, they were moved according to the tides. Would-be bathers then could enter the machine at the back fully clothed and emerge in a swimming costume straight into the sea.

Woman wearing a funny bathing suit at the Aquatic gala at Molitor swimming pool, on June 23, 1931 in Paris, France. Of course, that "funny" bathing suit with strategic cutouts is quite common these days.

The new "bikini" bathing suit (in a newsprint-patterned fabric because the the style statement would show up in all the papers), caused a sensation at a beauty contest at the Molitor swimming pool in Paris, July 1946.

Designer Louis Reard was unable to find a "respectable" model for his costume and the job of displaying it went to 19-year-old Micheline Bernardini, a nude dancer from the Casino de Paris. Here she is seen holding a small box into which the entire costume can be packed. Celebrated as the first bikini, Reard's design came a few months after a similar two-piece design was produced by French designer Jacques Heim.
